The problem I am having, is that I am not able to get these Odyssey batteries to charge properly in the Jeep Wrangler, because it has a very funky "smart charging system", that varies the charging voltage as you are driving to "save gas mileage".
Yep ! Pretty standard on almost every vehicle from about 2005.

All of the DC to DC chargers seem to want the starter battery separated from the accessory battery, as they already have an isolator built in.
Follow the instructions ! What you are missing is that theses DC-DC chargers actually boost the voltage going to the second battery so that it get the correct voltage no matter what is being sent to the starting battery.

The other option I am exploring, is just disabling the smart charging in the Jeep by disconnecting the Intelligent Battery Sensor. But this causes the alternator to put out a constant 14.5v, and I'm worried this will actually OVERCHARGE my batteries... but I'm not sure?
DON'T DO IT ! The computer module is very smart and trying to trick it, is not a good idea.
If the charging characteristics of the Odyssey AGM batteries are that different compared to a normal "flooded" lead acid, re-install a plain battery as your starting battery.
